The terabyte
The terabyte (TB) equals 10¹² bytes. Standard for hard-drive capacity. A 4K movie at typical streaming bitrate uses about 7 GB per hour, so 1 TB holds roughly 140 hours.
1 TB = 1000000000000 B
1 terabyte equals 1000000000000 bytes. To convert terabytes to bytes, multiply the terabyte value by 1000000000000. For quick reference: 1 TB = 1000000000000 B, 5 TB = 5000000000000 B, 10 TB = 10000000000000 B, 100 TB = 100000000000000 B.
Bytes = Terabytes × 1000000000000Start with your value in terabytes.
Multiply the terabyte value by 1000000000000. This is the exact conversion factor from terabytes to bytes.
The product is your value in bytes. For example, 5 TB × 1000000000000 = 5000000000000 B.
The exact factor from terabytes to bytes is 1000000000000.
Bytes = Terabytes × 1000000000000

A consumer NAS typically holds 4–32 TB across multiple drives. 1 TB of cloud storage is the standard 'pro' tier on most consumer plans.
The terabyte (TB) equals 10¹² bytes. Standard for hard-drive capacity. A 4K movie at typical streaming bitrate uses about 7 GB per hour, so 1 TB holds roughly 140 hours.
A byte is 8 bits — the smallest addressable unit on virtually every modern computer. ASCII text is one byte per character; UTF-8 ranges from 1 to 4 bytes per character.
